Question

The measures of two angles of a triangle are 72° and 58°. Find the measure of the third angle.​

Answer 1

Answer:

40°

Step-by-step explanation:

The sum of the three angles of any triangle is equal to 180 degrees.

So, 58° + 72°=140°

180°-140°=40°

Answer 2

ANSWER-

Let the measure of 3rd angle x.

So, 72°+58°+x= 180°

130°+x= 180°

Transpose 130° to R.H.S-

x= 180°-130°

x= 50°
